Mission and Description (December 1986)

The principal mission of the A-7D aircraft is the destruction of ground targets in support of ground forces. The A-7D is a single place transonic aircraft and has an all-weather combat capability.

The A-7D has fixed wing incidence and a high-lift system composed of leading edge flaps and single slotted trailing edge flaps.

Primary flight control is provided by outer panel ailerons, spoiler deflectors on the center section, unit horizontal tail and a rudder. A dual channel, three-axis, stick-steering autopilot is provided.

The fuel system incorporates both in-flight and single-point ground refueling capabilities. A Head-Up Display (HUD) system is provided to put all steering and attack displays between the pilot's eyes and the windshield.

A Navigation/Weapon Delivery system integrates many of the aircraft's avionic subsystems to provide for navigation to the target, computed run on target, computed weapon release, and return navigation.

There are two fuselage and six wing pylon store stations. A KB-18A strike camera system is located in the forward section of the engine compartment. 

A-7D in Combat
The A-7D began to arrive at Korat Royal Thai Air Force Base, Thailand, during the late summer of 1972. By the end of October, the A-7D had taken over the combat close air support (Sandy) mission from the Douglas A-1E Skyraider. The A-7D was also used during the closing months of the war as an escort on gunship missions and as a tactical bomber during the Linebacker II campaign. The development of the Head-Up Display (HUD) allowed the pilot to view all steering and attack information on a small display mounted above the main instrument panel between the windshield and the pilot's line of sight.

The A-7D was delivered in significant numbers to the Air National Guard -- many new from the factory. The ANG continued to improve the A-7D throughout the 1970s. One significant upgrade was the addition of the Pave Penny seeker system for detecting laser marked targets. The Pave Penny pod was mounted just below the engine air intake. The Pave Penny system was so successful it was incorporated in the A-10 design. Another improvement done by the ANG was the addition of advanced maneuvering flaps to increase the agility of the aircraft at low levels, especially during attack runs.

The National Museum of the United States Air Force has an A-7D on display. This aircraft was flown on Nov. 18, 1972, by Maj. Colin A. Clarke on a nine-hour rescue support mission in Southeast Asia for which he was awarded the Air Force Cross, the Air Force's second highest award for valor in combat.
